BONFIGLIOLI Vectron ACTIVE CUBE - Control of Frequency Inverter; Control via Contacts and Remote Contacts

11 Control of frequency inverter
The master sends its control commands (control word) via the output object PZD1 to
the frequency inverter and receives feedback about its status via a status word (sta-
tus word).
The frequency inverter can generally be controlled via three operation modes. The
operation modes can be selected via the data set switchable parameter L
o-
cal/Remote
412.

For operation with PROFINET, only operation modes 0, 1 and 2 are relevant. The
other settings refer to the control option via the KP500 control unit.

(Chapter 11.1)
The Start and Stop commands as well as the direction of
rotation are controlled via digital signals.

Control via
state machine
(Chapters 11.2, 11.4)
The frequency inverter is controlled via the control
word.
Only this setup supports positioning functions via
the control word and modes of operation.

Control via
remote contacts
(Chapter 11.1)
The Start and Stop commands as well as the direction of
rotation are controlled via virtual digital signals of the
control word.
Parameter Local/Remote 412 is dataset switchable, i.e. you can switch between the
different operation modes by selecting another data set. For example, a frequency
inverter can be controlled via the bus, and emergency mode can be activated locally
when the bus master fails. This switch-over is also identified by the status word (r
e-
mote bit).
Data set switching can be effected locally via control contacts at the digital inputs of
the frequency inverter or via the bus. For data set switching via the bus, parameter
Data set selection 414 is used.

With Data set selection 414 = 0, data set switching via contact inputs will be active. If
Data set selection 414
is set to 1, 2, 3 or 4, the selected data set is activated and
data set switching via the contact inputs is deactivated.
If Data set selection 414 is set to 5, data set switching via contact inputs will be a
c-
tive if the frequency inverter is not enabled.
Via parameter Active data set 249, the currently selected data set can be read. Ac-
tive data set 249 indicates the active data set (value 1, 2, 3 or 4). This is independ-
ent of whether the data set switching was done via contact inputs or
